T all 'wLoff/t it may] concern: Be it known that we, reunir Bnewna and Nomi G. BREWER, citizens of the nited States7 residing at Sidney, in the county of *ori e L the .oon

Cheyenne and State of Nebraska, have invented newv and useful inproven'ients in Oil-Burners, of which the following is a specification. i

rJhis invention relates to liquid fuel burners?l and more especially to those employing an overlying-retort; and the object of the same is to produce a burner for gasolene, kerosene, or crude oil which is capable of being placed entirely within a fuel box excepting its nozzle, the latter standing` ontside the iire door and opposite an opening therein.

@casting with the burner of tire specific type hereinafter described is a coarse granular material placed within said lire box so as to break up the llame issuing,T from the nozzle. lllithin the 'retort is tine granular meterial which serves es a ilterfor the oil. The ese of these materials may be said to be one of the features of the present invention.

The preferred construction of our burner is set forth in the following specification and shown in the sereni.; anying drawings el/herein iM J-mre fr a general side elevation partly breiten o1.: a diagram of this Complete inveiition es appiierl to e, ire boi;5 the letter being shown in section.

is slightly iii-ferent arrangement the oil tank, sV owingitlie use ot cornpressed air adrnitlteo, theieto to conse the flow of the oii.

Ifo do not Wish to claim specifically the lire boi; nor the door thereto; but as :i part of this invention We moire use of metal ceswe' Winch We will oeil a bor; l whose iront .im may be Closed a door EZ haring en open- 3, This box may weil be the ire bon of en ordinary stove, or that o* e fornace if the device of large The oil ifiows l: through a reed pipe 5 and l o to a retort rrhici latter is aifnple sito disposed Within and extending ho LI-on'eily through 'l nce the-npr 1 portion thereof; and in the retort within said bor: we form an arch 8 which normally rises from the plane of the remainder of the pipe 7 as seen in Fig. l. The inlet. end or the retort is vthe top of the connected by a coupling-,9- with theffe'ed pipe 5, and theoutlet end of the retort .isi connected by an elbow- 10 with the casing; of. a needle valve 11' having `alwhcel 12 J (miv its valve stem at the outer end anda nozzle 13 at its inner end directedfaxially toward Vthe opening 3 in the door 2. By preference said opeznngisoi about two :inches in diam-` etenand the tip' of 'the ,nozzle is1disposeel.'

about two inches awayfrom the plane of ihodoor, but these measurements may be' varied. when the device is made in extra large or" extra small sizes., l

Within the retort pipe throughout its length is iine granular material 15, such as gravel, and the saine serves as a filter for the liquid fuel. t will be obvious that by turning the retort on its axis the arch v8 may be caused to stand horizontal, and may be caused to depend from the remainin portion of the retort pipe if it `were not or the coarse granular material 16 with which tholowcr portion of the box 1 is illed.- This coarse material We preferably make in the forni of cubes or bricks, and it is quite possible to use Ordinar builders bricks promiscnously piled wit in the box l as shown in Fig. l. The unetion o these coarser g'ains or bricks is to break up the tierno, which latter burns at the tip of the nozle [i3 where sniiicient oxygen is received'io maintain combusti n. The coarse granular material or bricks 16 ybecome highly heated, and preserve the heat of the entire structure even aiter the supply of oil is out down to a minimum or perhaps out ofi? entirely. From time to time the retort pipe is rotated, as the coupling` 9 will permit. It is obvious that the line granular material 15 would slip or fall away from arch 8 and slide down the arms of the saine, thus leaving; a space at the top of the arch where the pipe contained nothing to talee up the excessive heat 'io which it was snojiected. Therefore tort be turned on side, one Way and then the other, and perhaps even to points at either side e little below the horizontal, the result would be that the granular ma* terial l5 would. be dislocl'ecl from its packedr condition in the an les between the arch and the straight portions of the retort ipe, and to an extent rea-distributed throng out the length of the arch, At long intervals the entire retort ipe will be removed and the .packing wit drawn and eplacedby other -ne granular material. he proper tiops and materials of parts are not essentia l 1 the oil doeslnot vow by gravity as seen 'mi 'Figi l. 1n order to cause it to How, this provided with an opening, and coarse granular :material within the lower portion vof said box; of a retort pipe having straight ends mounted through the ends of said box and an interposed arch overlying said coarse `granular material, fine granular material within said retort pipe and its arch, means for Supplying liquid fuel to one end of the rpipe, and a valved nozzle connected, with the other end of ythe pipe and directed toward said opening. f

2. In a liquid fuel burner, .the combina.- tion with a box having a door in one end provided with an opening, and coarse graaf ularv material within the lower portion of said'box; of a retort ipe passing transversely through the endg 'of said box above its coarse'granular material and containing within the box an upstanding arch, the pipe containing fine granular material, a liquid tank and supply pipe, a cou ling connecting such pipe with the inlet en of thel retort, a control valve in said inlet end, an elbow on the outer end 'of the retort ipe, and a valved nozzle carried by said elbow and directed toward the o ening in theboX-door,

vthe whole for use su stantially as described.

In testimony whereof we'ailx our sig.

natures.
